Description
Technical field
The present invention relates to turbo-charger technical fields, and in particular to a kind of turbocharger combustion gas exhaust gas intake and exhaust shell
Body.
Background technique
Turbocharger is to convert engine gas heat energy from waste gas to mechanical energy to improve engine charge pressure and density
And then promote the machinery of engine power.The combustion gas flue gas leading of turbocharger combustion gas exhaust gas intake and exhaust shell connection engine
Road bears engine vibratory loads, thermal stress load in work.Especially because engine space layout limits, booster whirlpool
Taking turns air intake casing, there are spatial offsets with engine gas exhaust pipe, when needing curved shape piping connection, gas inlet housing
Body bears vibration and the size and Orientation of thermal stress load is complicated and changeable, leads to booster combustion gas exhaust gas intake and exhaust shell work one
Occur housing distortion, crackle, the connection failures such as bolt looseness or fracture after fixing time, reduces booster safe operating life.Closely
Nian Lai, as engine emission index improves and diesel engine strengthening level improves, the exhaust gas temperature of turbine inlet also with raising,
Booster combustion gas exhaust gas intake and exhaust shell thermal stress load also increases accordingly.
As (1 is meridian housing in exhaust to Fig. 1 in figure, and 2 is are vented outer meridian housing, and 3 be the second connection bolt, and 4 be exhaust
Shell, 5 be turbine disc, and 6 connect bolt for first, and 7 be nozzle ring, and 8 be air inlet housing body, and 9 be latch structure) shown in, it is existing
In technology, turbine inflow water conservancy diversion inner cover and air inlet housing body 8 connect into overall structure by muscle, and nozzle ring 7 is in air inlet housing body 8
Be vented in the axial space that outer meridian housing 2 is formed, between the interior meridian housing 1 of exhaust and nozzle ring 7, when this space cold conditions
There is certain interval, due to expansion when hot, nozzle ring 7 is in axial compression state, has latch structure between nozzle ring 7 and gas inlet shell
9.The shell of 5 radial direction of turbine disc forms two walls, one cavity configuration by being vented outer meridian housing 2 and turbine case, when turbine disc
This structure, which has, when 5 accidental damage prevents damaged fragment (block) breakdown shell, pacifies fragment (block) packet in the intracorporal containing of shell
Global function.Existing structure booster turbine air intake casing and engine gas exhaust pipe there are when spatial offset, need by
When turbine inflow shell is designed to space bending shape or is connected with space bending shape pipeline transition, fired in turbine inlet high temperature
Under gas exhaust gas operating condition, when there is left and right or up and down asymmetric thermal stress load, it may appear that gas inlet shell and exhaust casing first
Bolt 6 is connected to loosen or be broken, outside exhaust casing 4 or air intake casing crackle, outlet shell or air intake casing flange distortion, exhaust
2 circumferential deformation unevenness of meridian housing leads to 5 top of turbine disc and the outer 2 inner wall gap of meridian housing of exhaust locally becomes smaller or part
Connecing mill leads to the failures such as turbocharger impairment.
